The 52-year-old is taking over from Peter Sterling and Bob Fulton after a disappointing 2017 State of Origin series.

Pearce recently signed a four-year deal with the Knights, leaving behind a decade of service at the Sydney Roosters.

After Cooper Cronk signed a two-year deal with the Roosters, everyone in the NRL wanted to know whether Pearce would stay to form one of the scariest halves combinations in the competition.

However Pearce chose to leave the nest, and signed with the Knights over Manly and Cronulla to begin a new chapter in his NRL career.

In his Sporting News column, Sharks captain Paul Gallen said the move may hurt Pearce's Origin chances, however Alexander believes that all players will get a look in.

“You always have to look at what’s gone on beforehand, it would be silly for me to say let’s have a clean slate and pick it on form,” Alexander told Big Sports Breakfast.

“We have to look at what players have done in Origin series, in particular last year and probably the year before. You have to look at how players handle certain situations.

“It doesn’t hurt Mitchell Pearce’s chances of playing (going to Newcastle). I applauded the decision. I thought it was fantastic for the game that Mitchell’s gone up to Newcastle.

“Mitchell had another very good year last year for the Roosters, he’s a quality player. There’s no doubt about it."

Alexander has spent quite a lot of time mentoring young Penrith halfback Nathan Cleary, a player who is bound to be brought up at the selection table in 2018.

Alexander believes he will be able to continue helping the 20-year-old progress further, despite his new role as NSW advisor.

“I’ll still be involved at Penrith – there’s no problem there,” Alexander said.

“If I’ve got to be the one to say to Nathan “sorry mate you’re not in this season” then so be it.

“Nathan and I work for 45 minutes a couple of times a week during the season. I don’t see there being a conflict of interest."

Alexander wasn't expecting the role within the Blues setup, but is welcoming the opportunity.

“It’s not something that I was thinking about. I really haven’t thought that much about Origin or being involved,” Alexander said.

“I think we’ve got a great group of senior players that have been there for a while, some that have only just arrived on the scene, and of course a good crop of young players that haven’t experienced Origin but are starring at club footy.”

The Panthers legend was asked about what his new role will actually have him doing.

“Officially it says I assist Freddie in picking the side, I assist him in camp and I assist him with the media duties,” Alexander said.

“I guess it’s those and probably more. We haven’t gone into detail exactly as to how he will run the camps, but I would like to be involved on the field – working with the halves, doing some kicking."
